- DEEP-WELL PUMP.

Specification of Letters Patent.

Patented May 18, 1915.

My invention relates to that class of deepwell pumps, in which a centrifugal, turbine or similar type of pump is located in the well or pit and is driven by a line-shaft which is parallel with but exterior to the discharge pipe of the pump. In this class of pumps, the line-shaft, which is usually of great length, has to be supported at proper intervals by suitable bearings, and

these bearings must themselves be supported and they must be lubricated.

It is the object of my invention to secure these results by simple and effective means, and to this end my invention consists in line-shaft bearings supported directly by the discharge pipe, and in the novel constructions and connections of said bearings for lubricating them, all as I shall now fully describe by reference to the accompanying drawings, in which-'- Figure 1 and Fig. l show a vertical section, broken, of my pump. Fig. 2 is a cross section, enlarged, on the line mw of Fig. 1*. Fig. 3 is a cross section, enlarged, on the line yy of Fig. 1". Fig. 4 is a cross sectional view showing two discharge pipes and a form of supporting clamps adapted for this construction.

1 is a pulley through which power is applied to the vertical line shaft 2 mounted in bearings 3 and 4, located in the frame 5 and the discharge elbow 6 respectively.

7 is the well-casing.

The vertical line shaft 2 communicates power from the pulley 1 to the impeller or impellers 8 contained in the pump body 9, located within the well casing 7.

Attached to the pump body 9 is a three port discharge manifold 10 designed to deliver the water discharged from the pum into the discharge pipe or pipes, of whic three are shown here, designated by 11. More or less than three discharge pipes may be employed for the above service without aflecting the spirit of this invention; thus in Fig. .3 I have shown .three, while in Fig. 4 I have shown two discharge pipes. The

. 13 of the next bearing below.

former construction is adapted for a small or circular well, while the latter constructlon is best for a larger or rectangular Well or pit.

Located at intervals, say, every five feet, more or less, along the length of vertical. line shaft 2 are bearings, the bodies of which are indicated by 12. The bearing bodies 12 are provided with oil receiving-chambers 13 and oil discharge-chambers 14. These two chambers are connected by vertical passages 15 which permit the overflow and the passage by gravity of the oil from the receiving chambers 13 to discharge chambers 14. In the form of supports for the bearings, shown in connection with the three discharge pipes, the bearing bodies 12 are provided with tapped holes to receive studs or bolts 16, which studs or bolts by means of nuts 16' are used to tighten the clamps 17 upon the vertical discharge pipes 11, and to draw said discharge pipes firmly against said bearing bodies 12, whereby said bodies are supported by said pipes. A recess or oil pocket 18 is provided in each oil receiving chamber 13 for the accumulation of suflicient oil for lubricating the journals on vertical line shaft 2. Oil pipes 19 conduct the surplus oil from the discharge chamber 1 1 of each bearing to the receiving chamber Oil which leaks by each journal is thrown outward by the revolving oil collar 20 and is caught in the discharge chamber 11, being prevented from leaking past shaft 2 by the raised annular rim 21. The set collar or sand-cap 22 is to prevent the entrance of sand and dirt to the bearing body 12.

23 is an oil supply tank for feeding oil into the oil box 24 located just over the discharge elbow bearing 4 at the top of the well. From this box a pipe 24 leads the oil to the receiving chamber 13 of the first bearing 12. While oil is mentioned as the lubricant for the bearings above the water line in the well, it may be convenient and practical at times to run water through pipes '19 as a substitute for oil.

tical thrust during the operation of the pump.

A discharge flange 26 carrying the discharge elbow 6 is provided to cover the top bearlng; a

of the well and to support the vertical discharge pipes 11, which pipes in turn support and hold in alinement the bearings 12, and support the pump at their lower ends. The discharge pipes 11 are fastened to said discharge flange 26 by means of'nuts 27 which are screwed to give the required adjustment.

It will be observed that the arrangement described provides for great compactness, thereby allowing the pump'to be lowered into a well ofsmall cross sectional area. It is of comparatively cheap construction, and the bearings can be readily inspected by raising the pump from the well. Those bearings which happen to be submerged will be water lubricated, while those above the level of the water in the-well, will be lubricated with oil from the supply coming from the receptacle next above.

In Fig. 4, I'show a form of support for the bearings, adapted for two discharge pipes. The bearings and pipes are here designated by the same numerals as in the other figures. The clamps 28 in this case consist of a pair of opposing members properly embracing the pipes and bearings and held by bolts 29.
